As part of the Change Project, researchers at Open University conceived the Lambent Shopping Trolley Handle. The 16-LED multicolor display and scanner attaches to any supermarket cart and gives shoppers nutritional, ethical and environmental product information. It also allows users to compare their choices with those of other consumers in order to gauge just how socially conscious they’re being.
Displaying this information “generated a significant nudge effect, influencing what products people selected,” says user experience researcher Vaiva Kalnikait?.
